Abstract
A negative pressure wound therapy system can include a wound dressing configured to be placed over a wound and configured to absorb fluid. The system can include a source of negative pressure configured to generate negative pressure to aspirate fluid from the wound. The system can include a memory. The system can include a controller configured to periodically store a plurality of data sets in the memory, in response to storing a data set of the plurality of data sets at a memory address in the memory, update the memory address for storing a subsequent data set, and in response to determining that the memory address corresponds to a memory address indicative of a duration of time following an initial activation of the system reaching a total permitted operational time of the system, provide an indication that the total permitted operational time of the system has been reached.
Claims (27)
1. A negative pressure wound therapy system comprising: a wound dressing configured to be placed over a wound of a patient, the wound dressing configured to absorb fluid; a source of negative pressure configured to generate negative pressure to aspirate fluid from the wound; a memory; and a controller configured to: periodically store a plurality of data sets in the memory; in response to storing a data set of the plurality of data sets at a memory address in the memory, update the memory address for storing a subsequent data set; and in response to determining that the memory address corresponds to a memory address indicative of a duration of time following an initial activation of the system reaching a total permitted operational time of the system, provide an indication that the total permitted operational time of the system has been reached.
2. The system of any of the preceding claims, wherein the controller is configured to store each data set of the plurality of data sets at an expiration of a time interval.
3. The system of claim 2, wherein the time interval is fixed.
4. The system of any of the preceding claims, wherein the data sets are of a fixed size.
5. The system of any of the preceding claims, wherein the controller is configured increment the memory address by a size of the data set.
6. The system of any of the preceding claims, wherein the memory address indicative of the duration of time reaching the total permitted operational time of the system is determined based on a frequency of storing the data sets in the memory, size of the data sets, and the total permitted operational time of the system.
7. The system of claim 6, wherein the memory address indicative of the duration of time reaching the total permitted operational time of the system is determined by multiplying the frequency of storing the data sets in the memory by the size of the data sets and the total permitted operational time of the system.
8. The system of any of claims 6 to 7, wherein the memory address indicative of the duration of time reaching the total permitted operational time of the system is further determined based on a size of data configured to be stored at the memory address.
9. The system of any of claims 6 to 8, wherein the total permitted operational time of the system comprises 7 days, 10 days, or 14 days.
10. The system of any of the preceding claims, wherein the plurality of data sets comprise data related to provision of negative pressure therapy.
11. The system of any of the preceding claims, wherein the indication that the total permitted operational time of the system has been reached comprises disabling generation of negative pressure by the source of negative pressure.
12. The system of any of the preceding claims, wherein the memory comprises nonvolatile memory.
13. The system of any of the preceding claims further comprising a power source configured to power at least one of the source of negative pressure, the memory, or the controller.
14. The system of any of the preceding claims, wherein at least one of the source of negative pressure, the memory, the controller, or the power source is disposed on or within the wound dressing.
15. A method of operating a negative pressure wound therapy system, the method comprising, by a controller of the negative pressure wound therapy system: periodically storing a plurality of data sets in a memory of the negative pressure wound therapy system; in response to storing a data set of the plurality of data sets at a memory address in a memory of negative pressure wound therapy system, updating the memory address for storing a subsequent data set; and in response to determining that the memory address corresponds to a memory address indicative of a duration of time following an initial activation of the system reaching a total permitted operational time of the system, providing an indication that the total permitted operational time of the system has been reached.
16. The method of claim 15, further comprising storing each data set of the plurality of data sets at an expiration of a time interval.
17. The method of claim 16, wherein the time interval is fixed.
18. The method of any of claims 15 to 17, wherein the data sets are of a fixed size.
19. The method of any of claims 15 to 18, further comprising incrementing the memory address by a size of the data set.
20. The method of any of claims 15 to 19, wherein the memory address indicative of the duration of time reaching the total permitted operational time of the system is determined based on a frequency of storing the data sets in the memory, size of the data sets, and the total permitted operational time of the system.
21. The method of claim 20, wherein the memory address indicative of the duration of time reaching the total permitted operational time of the system is determined by multiplying the frequency of storing the data sets in the memory by the size of the data sets and the total permitted operational time of the system.
22. The method of any of claims 20 to 21, wherein the memory address indicative of the duration of time reaching the total permitted operational time of the system is further determined based on a size of data configured to be stored at the memory address .
23. The method of any of claims 20 to 22, wherein the total permitted operational time of the system comprises 7 days, 10 days, or 14 days.
24. The method of any of claims 15 to 23, wherein the plurality of data sets comprise data related to provision of negative pressure therapy.
25. The method of any of claims 15 to 24, wherein the indication that the total permitted operational time of the system has been reached comprises disabling generation of negative pressure by a source of negative pressure of the negative pressure wound therapy system.
26. The method of any of claims 15 to 25, wherein the memory comprises nonvolatile memory.
27. A non-transitory computer readable medium storing instructions that, when executed by a controller of a negative pressure of the negative pressure wound therapy system, cause the controller to perform the method of any of claims 15 to 26.
